Stable open-circuit voltage values above 1 V were successfully obtained with thin film electrolyte cells, which implied that the 1 mu m thick electrolyte was fairly dense and gastight. The thin film electrolyte cells exhibited a much more improved cell performance than a thick film (similar to 8 mu m) YSZ electrolyte cell at the low operating temperature regime (350-550 degrees C) and, in some cases, showed better power outputs than other thin film membrane micro-SOFCs.
